On recent -CURRENT, to build world using the version of gcc in base, and to not build or use the version of clang in base at all, you need at least the following settings in your src.conf: WITH_GCC=x # Enables building gcc for the final world WITH_GCC_BOOTSTRAP=x # Enables building gcc during cross-tools WITH_GNUCXX=x # Enables building libstdc++ and libsupc++ WITHOUT_CLANG_BOOTSTRAP=x # Disables building clang during cross-tools WITHOUT_CLANG=x # Disables building clang for the final world WITHOUT_CLANG_IS_CC=x # Links gcc to /usr/bin/cc, /usr/bin/c++, etc. Note that you can delete WITHOUT_CLANG from your make.conf, just like other WITH_ and WITHOUT_ settings. These only belong in src.conf. -Dimitry --Apple-Mail=_C9EA2FBB-7655-4E76-89FB-762AC2338744 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.26 iEYEARECAAYFAlRhEcQACgkQsF6jCi4glqPl9ACeM95WluQbVVPHhnilvZyGtgC0 VaoAoIsxHKOmpAtwAOCi+Vu7W1XVWME8 =bJCw -----END PGP SIGNATURE----- --Apple-Mail=_C9EA2FBB-7655-4E76-89FB-762AC2338744--
